MINITAB can create the analysis of variance table for Example 1 concerning recycled road materials. The three levels of \(A\) are coded 1,2, and 3, and the two levels of \(B\) are coded 1 and 2. The third column contains the values of the resiliency modulus.

To obtain the two-way table of means, click on Results and type \(A * B\) in the Display means box. Then, click OK.
Repeat Exercise 13.1 using computer calculations.
